vapi: Missing include file in vlib.api.vapi.h

- A call to vapi_msg_control_ping_hton() is generated in
  a static inline function in vlib.api.vapi.h, which is
  defined/generated in memclnt.api.vapi.h without
  including memclnt.api.vapi.h in vlib.api.vapi.h.
  This breaks the compilation of plugins which include
  only vlib.api.vapi.h (e.g. hicn_plugin from the HICN
  project).

Type: fix
